When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -8c + c = -9c + 3z + 9 for c in terms of z.
| \(\frac{1}{3}\)z - \(\frac{1}{3}\) | |
| 2z + 9 | |
| -5z + 4 | |
| 10z - 7 |
